FLUGROSCOPC STAND.

Application filed November la, 1922. Serial No. 600,812.

This invention relates to an X-ray apparatus, and particularly pertains to a fluoroscopic stand.

In making X-ray examinations of the internal organs, it has been found essential to proper exploration and diagnosis that the subject be turned at different angles to the observer so that the exact condition of the parts under observation can be more readily observer.. At the present time it is common practice to require the patient to move from one angle of vision to another, and this has led to confusion and inaccuracy, it being the object of the present invention to provide means for iixing the patient relative to the X-ray tube and the .screen and to insure that the angular position of the patient may be accurately determined for immediate observation or for repeated observation at different times.

rl`he present invention contemplates the use of a revoluble back rest, which back rest may be turned to a desired angle and set, the angle being easily read in the dark by an illuminated member carried by the platform.

The present invention is illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a view in side elevation showing the invention used while in an upright po'- sition.

Fig. 2 is a view in plan, particularly the base of the device and the ink g means carried thereby.

F ig. 3 is a view in side elevation showing the device when disposed horizontally.

is a View in perspective showing another form of the present invention.

Referring more particularly to the drawings, 10 indicates a base. This member is here shown as rectangular in section and as having graduations 11 formed upon its upper face. These graduations are arranged concentrically around a pivot pin 12, :upon which pin a platform 13 is pivotally mounted. The platform is adapted to rotate around the pin and to rest upon bearing casters 14 which travel along a channel trackway 15. .Y

Secured to the rear edge of the platform 13 and extending at right angles thereto is a back rest 16. This rest is preferably'eoncaved so that it will serve as a comfortable support for the back of a patient, while either in a horizontal `or vertical position. Diagonal braces 17 serve to reinforce the .back rest and to more rigidly secure it in relz ion to the platform. A pointer finger 13 is secured centrally of the forward edge of the platform 13 and is adapted to register with the various graduations 11.-

ii recess 1S is formed in the edge of the platform adjacent the mounting of the pointer to receive a box 19 carrying a lamp socket 2O and incandescent lamp 21. rllhe outer'face of this box is preferably closed by a glass 22, through which the rays of light from the box may fall on the dial graduations. Y In some instances it may be desirable to dispose the patient inl a horizontal position while making an observation, and with that purpose in view an auxiliary s pport 23 has been provided. This support is secured to a pivot casting 24 by a removable pin25. rlhe casting 24 is fixed to the upper end of the back rest 16 and has a bearing at its outer end which is in longitudinal alignment with the pivot 12 of the base. 1t will thus be evident that by turning the stand down as shown Vin F ig. 3 it will be swung from the pivot pin 25 and the pin 12 while utilizing the base 10 and the auxiliary member 23 as supports. The back rest and platform may be lockedA in any desired position 'by means of a pin 26 which is securet to the edge of the platform within'a bearing 27. This pin is spring pressed against the upper face of the base 10 and may be lifted to permit the platform to turn, after which the 'spring will again hold the pin against the basein a manner to prevent turning of the platform.

Reference being` had to Fig. 4.- of the drawing, it will be seen that instead of revolving the platform upon which the patient stands, the platform is made stationary and the back rest 29 revolves. This rest is provided with straps 30 by which it may be positioned against the body of the patient. The rest is supported by a rod 31 and may be adjustably held relative thereto by a bearing 32 and a set screw The upper end of the rod 31 is pivoted for horizontal rotation from a plate 34. This plate carries a dial 35 similar to that shown in Fig. 2 of the drawing.y A pointer 36 is carried by the rod and moves over the face of the dial so that the position of the patient inay be accurately determined in the saine manner and for the saine purpose as previously described.

n operation of the present invention it will be `assumed that thepatient is disposed in a vertical posid as niight be the case when heart observations are taken.V j By causing the patient to stand squarely on the plattorin and lean against the back rest will be possible for this position to be held 'for a considerabletiine `without fatigue. rifhe observations inay then be taken at any desired angle by inerely swingingl the stand upon its pivot l2 and locking' the stand by releasing the lock pin 26. rine angle would be determined by registration ot' the Vingers 1 8 With the graduations of the dial. vit will also be observed that one ot these lingers is secured in the rear ol the bark rest, thus making it possible to completely reverse the patient and to still accurately set the platforin.

1When it is desired to place the patient in a horizontal position, as when intestinal observations are to be made, stand may be turned with the haelt rest horizontal, alter Which the support 2B is secured to the ineinber 24 by the pin it will thus be seen that tlie device here disclosed provides a siniple and convenient ineans for rapidly and accurately'disposing a subject in a desired position relative to an -ray apparatus.

lli/Thilo WeV have shown the preferred form of our invention, as noiv known to us, it Will be understood that various changes might be inade in thewconibination, construction and arrangement of parts bythose skilled in the art, Without departing from the spirit oit the invention as claimed.

Having thus described our invention,

ive claiin and desire to secure by Letters `Patent is:

l. iuoroscopic stand comprising` a-plattorni, a base ineinber upon Which it is revolubly niounted, a back rest carried by the platform, a bear' secured at the opposite end of the back rest frein the platorin and an auxiliary supporting device adapted to oe pivotally secured to the bearing and to cooperate with the base in pivotally supporting;V the back rest in a horizontal position. Y

tiuoroscopic stand comprising` a platiforni, a base nieinber upon which it is revolubiy mounted, a baclA rest carried by the plattform, bearing secured at the opposite end o the back rest troni the platt'orni, an auxiliary supporting. device ad nted to be pivotally secured to the bear d to cooperate with the base in piv-V @tally supporting the back rest in a hori- Y rental position, and ineans 'lor securingl the Y plattorni at a desired angle to the base.
